About IronstoneHide

Lithified iron-rich sediments.

Any rock containing a substantial proportion of an iron compound, or any iron ore from which the metal may be smelted commercially; specif., an iron-rich sedimentary rock, either deposited directly as a ferruginous sediment or resulting from chemical replacement. The term is customarily applied to a hard, coarsely banded or nonbanded, and noncherty sedimentary rock of post-Precambrian age, in contrast with banded iron formation. The iron minerals may be oxides (limonite, hematite, magnetite), carbonate (siderite), or silicate (chamosite); most ironstones containing iron oxides or chamosite are oolitic.

See: clay ironstone, banded ironstone [glossary item missing]

Compare with: iron formation
